ISS primarily focuses on what are commonly called TIS or Traveler Information Stations.
These stations operate in the AM Broadcast Band (530 kHz - 1700 kHz), are limited to a 10 watt transmitter output power and the antenna height may not exceed 15 meters (49.2 feet). A TIS may not transmit commercial information and this service is not available to individuals or groups - only to governmental entities and park districts. What unexplored opportunities await in the 10-watt world of TIS?
